Hi there - I have caught a few of your posts over the last week or so. It sounds like you are on the ol' anxiety roller-coaster right now! You should not let your anxieties and stop you losing weight and getting healthy.
Try to remember that pancreatic cancer is an incredible rare condition. Incidence rates start to go up after age 60, but at 42, the chances of you having it are incredibly small. I know in one of your posts, you mentioned reading that Patrick Swayze reportedly had a symptom that you also have so you had made the link to pancreatic cancer fear. This is absolutely, 100% your health anxiety talking.
Have you spoken to your Doctor about your symptoms?
